Title: Bubble memory organization with two port major/minor loop transfer
IPC: G11C11/14
Filed: 1974-12-18
Abstract: 1486819 Magnetic domain devices TEXAS INSTRUMENTS Inc 18 Dec 1974 [28 Dec 1973] 54736/74 Heading H3B A bubble memory includes minor loops 12-16 and a non-closed major "loop" 40 such that bubbles travelling in the major loop pass adjacent the minor loops twice and in the same order. As shown the bubbles move counterclockwise and one-way (or two-way) gates permit transfer from the minor to major loop at 46-42 and vice-versa at 56-52. Conventional read, write, generate and annihilate devices such as 48, 50 are provided and may be replicated at 49, 51 so that bubble propagation may be reversed by reversing the rotating field sequence instead of circulating bubbles by transfer between the major and minor loops. Two sets of minor loops (Fig. 6, not shown) may be associated with a single major "loop" so that bubbles pass the sets alternately and on alternate sides. The memory structures are otherwise conventionally formed of garnet or gadolinium cobalt on a non-magnetic garnet substrate and with a permalloy overlay.

Abstract: 1,236,806. Electric couplings. FORD MOTOR CO. Ltd. 19 Nov., 1968. No. 54748/68. Heading H2E. To prevent inadvertent reversal of polarity of a car battery, a positive contact 16, crimped to a lead at 19 and bolted to a positive battery terminal 10 at 14, is longer than a negative contact 17, bolted at 15 and having a flange 18 which abuts the side of a negative terminal 12, which is shorter and thinner than terminal 10, the net effect being (1) that positive contact 16 is too long to abut negative terminal 12 and be bolted at-15 (with ferrule 19 at the top of the terminal); and (2) flange 18 and ferrule 19 prevent negative contact 17 from abutting positive terminal 10 and being bolted at 14 (with ferrule 19 at the top of the terminal). Each contact, made of sheet metal, e.g. tinplated brass, may be secured to its terminal, of lead or lead alloy, with a square nut which abuts a terminal base 20, 21 of lead or lead alloy.
